Do all dogs have this?
we have recently adopted a 6 month old dog. and we got him nuetered. one day when i came home from school i went into my sisters room and the dog was hapopy to see me. he was barking and jumping and when i sat on the bed he flopped on the bed. when he did this i seen a red thing coming out of his penis. i told my sister that he was bleeding but she said that all dogs do this when they get excited. i found it disgusting and left the room. do all recently neutered dogs have a red thing come out of there penis. f.y.i it wasn't blood like i thought
